A 1 L bottle of air is sealed at room temperature (23 \"(3) and atmospheric pressure (100.4 kPa) before being stored in a refrigerator at 32C. After the air in the bottle reaches thermal equilibrium with the air in the fridge, what is the pressure in the bottle? Provide your answer in HM with 3 SF. (0C corresponds te 213.15 K.) Type your answer... 29 A 933 L tank holds an ideal gas at a pressure of 4.2 kPa. What is the total translational kinetic energy of the gas molecules inside the tank in kJ? Provide answer to 4 SF.30 A steam engine has a boiler that burns fuel at a temperature of 502 K. The energy from the burning fuel changes water to steam, and this steam then drives a piston. The cooled steam is released to the outside air, which has a temperature of approximately 306 K. What is the maximum possible thermal efficiency of this steam engine? Provide the answer to 2 SF. Hint: to find the maximum possible efficiency, imagine a Carnot steam engine. Type your
